Buckingham Palace says Queen Elizabeth II had successful eye surgery to treat a cataract last month.

21 April in London hosted a star-studded concert in honor of the 92nd birthday of Queen Elizabeth.
The Press Association news agency said Britain's longest-reigning monarch, who has been on the throne for more than 66 years, underwent the surgery, the most common operation performed in the United Kingdom, at London's private King Edward VII hospital.
The palace made the announcement Friday after the queen was seen wearing sunglasses at a number of recent public engagements.

Cataracts are cloudy patches on the eye's lens which can cause blurred vision and eventually blindness.
The Queen Mother had an operation to remove a cataract from her left eye when she was 95 in 1995, but after her surgery she spent a night in King Edward VII hospital, unlike her daughter.
The last time Queen Elizabeth was in hospital was in 2013 at age 86 after she suffered a bout of gastroenteritis.
The procedure typically takes 30 to 45 minutes and usually requires the surgeon to make a tiny cut in the eye to remove the cloudy lens and replace it with a clear plastic one.
Next Thursday, in an appearance sure to be closely watched, she will spend a day in Cheshire in northwest England near Liverpool with none other than her newest granddaughter-in-law, Duchess Meghan of Sussex, 36.
